"WILLIAM F. LINDSEY, OF SADLER, TEXAS.

PLOW.

To all whom it may concern:

Be it known that I, l/VILLIAM F. LINDSEY, a citizen of the UnitedStates, residing at Sadler, in the county of Grayson, State of Texas,have invented certain new and useful Improvements in Plows; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to plows, more particularly to shovel plows, andhas for its object to simplify and improve the construction and increasethe efficiency and utility of devices of this character.

With these and other objects in view the invention consists in certainnovel features of construction as hereafter shown and described and thenspecifically pointed out in the claim, and in the drawings illustratingthe preferred embodiment of the invention.

Figure 1 is a side elevation of the improved plow. Fig. 2 is a plan viewin section on the line 2-2 0f Fig. 1 with the handles removed. Fig. 3 isa section on the line 3 3 of Fig. 1 with the handles and braces removed.

The improved device comprises a beam 10 of the usual construction andpreferably of steel, with handles 11 connected thereto at l2 and withbraces 13 between the handles and the beam. Attached to the oppositesides of the beam at its lower or foot portion are two runners 14-15spaced apart a distance equal to thethickness of the beam and extendingboth forwardly and rearwardly thereof. At the rear end of the runners acutter element 16 is mounted to swing upon a pivot 17 near its forwardend, the rear end of the cutter being provided with a plurality ofapertures 30 to receive a clamp bolt 18 extending through the runners sothat the cutter element may be adjusted vertically to increase ordecrease the depth of the cut, as hereafter more fully explained.

The forward ends of the runners are formed with upstanding transverselyperforated ears 15, toreceive a bolt 23 by which the runners areconnected with the standard, presently to be described. Back of the earsthe runners are laterally deflected to provide shoes 19 and 20 thatoperate to cause the mold board to cut to a determined depth. As will beseen by reference to Fig. l the shoes wedge into the ears on curvedlines, and this specifieation of Letters Patent.

will materially facilitate the passage of the mold board through thesoil, as there will be no abrupt surfaces against which the earth canpack. Pivotally connected to the forward ends of the runners by the bolt23 is the standard, which as shown in Fig. 2 is composed of two spacebars 21 and 22, the forward ends of which are inset to fit between theears 15".

The standard members are curved rearwardly and upwardly and thenceextended obliquely rearwardly of the beam 10 and bear against the sidefaces thereof, and are provided with transverse apertures forw'ardly andrearwardly of the beam, the apertures being designed to receive clampbolts 2li- 25 by which the standard members may be adjustably clamped tothe beam. By this arrangement it will be obvious that by loosening thebolts 211-25 the standard may be adjusted to any required extent uponthe beam.

Bearing upon .the standard members 21-22 is the mold-board 26 having itsnose 27 extending forwardly of the forward ends of the runners.Extending through the mold-board near its lower end is a clamp bolt 28,the head of the bolt fitting into a countersunk cavity in the face ofthe moldboard and the opposite end provided with a nut 29, the latterbearing against the under sides of the standard members 21-22 andfitting into therecesses formed by the offsets 19-20 of the runners, therecess formed by the lateral portions 19-20 adapted to receive the nut29 and enable a wrench to be applied thereto when required. By thissimple means the mold-board may be readily attached and detached forsharpening or for renewal and may be likewise adjusted upon thestandard, while the standard itself may be adjusted to change theinclination of the mold-board and thus control the depth of the cut.

The cutter member 16 may be adjusted to operate at any depth below therunners, to adapt it to' the condition of the soil through which theplow is operating, and controls and steadies the plow, and preventslateral movement or wabbling.

It will be observed upon reference to the drawings that the shoes 19 and20 are below and slightly in the rear of the plow and serve to bear inthe bottom of the furrow and resist any tendency of the plow to runlower in lthe 'soil and aid materially invkeep-V` l cally into and belowthe bottom of the uri row serves to direct the plow ina straight lineand :prevents wabbling `t-hereo`- lt will be further observed that .inorder to guide the plow when working a soft or loamy soil, n

it'is vnecessary that the ledge of lthe cutter project deeper 'to'prevent lateral 'movement than would be 'the Acase if the plow wereoperating in aol'ay or any soil difficult to wor'lr and the adjustablenature of the cutter heretofore described attains "this end.

`'llhe vdevice is simple in construction, can be inexpensivelymanufactured, and operates satisfactorily for the purposes described.

What is claimed, iszy In a -p-low, the combination with a beam,

yfof runners provided `at their forward ends with upstandingtransversely perforated ears; a pair of outwardly and downwardlyextending shoe members formed integral with said runners adjacent saidears kfor presenting anenlarged horizontal surface to the soil; a pairof cutters pivoted to the rear ends of said runners; and means foradjusting said cutters so that their cutting4 edges may be kprojecteddownwardly to a greater or less extent.

In testimony whereof, I affix my signature, in presence `of twowitnesses.
